As a copy editor, one of the most important grammatical rules to master is subject-verb agreement. This rule states that the subject and verb in a sentence must agree in number (singular or plural). While this may seem like a basic concept, it is essential to communicate ideas effectively and maintain a professional tone in your writing.

To properly understand subject-verb agreement, it is crucial to first know what constitutes a subject and a verb in a sentence. The subject is the person, place, thing, or idea that the sentence is about. The verb, on the other hand, is the action or occurrence that the subject performs or experiences.

For example, in the sentence “The dog chases the cat,” “dog” is the subject, and “chases” is the verb. The two must agree in number, meaning that if the subject is singular, the verb must also be singular. If the subject is plural, the verb must be plural as well.

Here are some examples that demonstrate subject-verb agreement:

– Singular subject: The boy runs to school.

– Plural subject: The boys run to school.

Note that in the second example, the verb “run” is plural to match the plural subject “boys.”

However, subject-verb agreement can be more complicated when dealing with compound subjects or indefinite pronouns.

Compound subjects are two or more subjects in one sentence. In this case, the verb must agree with them both in number. For example:

– Compound subject: The dog and the cat chase the mouse.

– Indefinite pronouns: Each of the boys runs to school.

Finally, it is vital to pay attention to subject-verb agreement when writing for SEO. Search engines are becoming increasingly sophisticated in their ability to analyze the content of web pages, including sentence structure and grammar. Proper subject-verb agreement can help improve your website`s search engine visibility, so it is worth taking the time to master this concept.

In conclusion, subject-verb agreement is a fundamental grammatical rule that is essential for effective communication in writing. By understanding this concept and applying it appropriately, you can ensure that your writing is clear, concise, and professional. As a copy editor, it is your responsibility to ensure that all content follows this rule and is optimized for search engine visibility.
